Application filed June 12,

T 0 all whom it may concern l3e it known that I, HARRY. "W. Jones, a citizen of the United States, residing in New York in the county 0t New York and State 0t 1 ew York, have invented a new and usetul Improvement in Sitter Tops, 0t which the following is a specification.

This invention relates in general to sitter top cans and has tor its object broadly the provision 0t new and improved construction in cans having tops ot this character wherein sitter openings are provided by the manipulation by the user ot the material ot the can and without providing any separate member or members tor the closing ot the perforation or sitter openings.

A principal object of the present invention is the provision ot a construction in which the sitter openings will be tightly closed when the can is received by the user and which will permit ot the establishment of sitter conditions by the user and through the exertion of a lightly applied pressure to the can wall or end. The invention contemplates in this respect a construction wherein the sitter openings may be provided by the user through and as a result ot pressure exerted by his hand upon an appropriate portion ot the can end.

Another principal object ot the invention is in providing sitter openings in a can top that are spirally disposed so that as the uncut center panel is pressed inward to pro duce the sitter openings the panel has a spiral rotating motion.

It has been found that in slitting the metal top in this manner in the fiat that I am able to press the severed portions back into position to close the slit openings and make them sufliciently tight tor ordinary powdered substances. 7

Another important object of the invention is the provision ot a disintegrator extending inwardly ot the can trom the sitter end.

Another important object of the invention is the provision ot a can having these and other advantages which will not require the provision 0t additional parts or additional material and which will be cheap to manutacture and 0t distinctive and pleasing appearance.

Numerous other objects and advantages ot the invention will be apparent trom the tollowing description, when tak n in connec- 1920. Serial No. 338,536;

tion with the accompanying drawing which illustrates preterred embodiment thereot.

arrangement betore the can end is pressed by the user to provide the sitter openings: and

3 is a view sim lar to Fig. 2 showing the arrangement atter the sitter openings are provided.

F or the purpose ot illustrating my invention T have shown on the drawing a can body 10 0t any usual or preterred construction and material and having seamed to it at 11 an end wall or closure 12. This end wall is provided with a plurality 0t curved or spiral lines ot severance 13 extending out trom a central part 14. The lines of severance 13 are tormed by cutting through the material and pressing the material back thereafter to its original or normal position, which in the present instance is in the plane or" the remaining part ot the end 12. This results in the provision ot a-flap end as shown in Fig. 2 and the central part 14 may be pressed down by pressure ot the thumb to cause the structure to take a setas shown in Fig. 3. This results in the provision ot sitter openings 15 along the lines ot cut or severance, as shown in Fig. 3 and also provides a disintegrator within the can.

The lines ot out are apparent upon the can when it is received by the user and produces an attractive configuration resembling a rosette.

It is thought that the invention and many ot its attendant advantages will be apparent trom the toregoing without turther description, and it will be apparent that various changes may be made in the term, construction and arrangement ot the parts without departing trom the spirit and scope ot the invention or sacrificing all ot its material advantages, the torm hereinbetore described being merely a preterred embodiment there- 0t.

1 claim:

to provide openings along said lines of severance.

2. A can Wall having severed lines defining strips connecting a part in the center of said lines of severance With the part With- A out, the same central part being capable of being depressed to separate said strips to provide a dis'integrator Within the can.

8. A can Wall having severed lines defining strips connecting a part in the center of said lines of severance With the part Without, the same central part being eapable of being depressed to separate said strips to provide sitter openings between 4. A can Wall having severed lines extending spirally from near a common center, said center being capable of being depressed to provide openings on said lines of severance.

5. A can Wall having a portion from Which curved lines of cut extend out iniall direc tions said lines of out being formed by cutting through the material and pressing the material back to close said lines of cutsaid material being capable of being subsequently depressed to provide openings on said lines of cut.

6. A can Wall provided with the lines of cut disposed about a part adapted to be depressed to produce separation on said lines of out, said part being normally in the plane of the can wall and said lines or out being formed by severing the material, and 010s ing spaces formed on the lines of out in the severing operation by returning the material to its original plane.
